We could say that FootFeed is an aggregator of different web services that will let you check in everywhere in a fell swoop. That is, by integrating the APIs of websites like Foursquare, Brightkite, and Gowalla together FootFeed empowers you to check to all of them simultaneously.
The one indisputable advantage that this has got is that you will be able to earn points, badges and mayorships from multiple services by merely checking in once. And you will also be capable of seeing all your friends in a single feed.
For its part, companies that are interested in adding multiple check in capabilities to any app that they are designing can always go for FootFeed’s API in order to implement such a functionality.
And I didn’t mention it above, but support for Facebook is also included as it is only fit – when the day comes, Facebook Places is set to explode all over the Internet. That is something that every other universal check in application will have to take into account from this point onwards.
